The first photo is slightly blue. Also there is a blue color fringing around the index finger and a halo around the other.
The second has motion blur
The third photo also has a white balance issue and IP issues. The hand is looking slightly blue.
ALE1345 has a white balance issue. Photo edge is looking soft.
The issues seem to be common among all your files. White must be white. You need to get the colors as close to reality as possible. Make sure your camera is focused before taking the shot. Adjust shutter speed to compensate for motion. Do post-processing to remove trade marks and logos, correct noise, exposure, etc.
_ALE1345-Editar.jpg - composition is an issue. You should have repositioned the model so his limbs weren't cut off and he wasn't competing for space with the furniture. There's also part of a logo showing on his sweatpants.
ALE1576-Editar.jpg - composition is also an issue here, with part of the woman's arm cut off. Areas in the background are also overexposed.
ALE1459-Editar.jpg - leaning verticals; not focused on wi man's face; man seems superfluous in this scene
ALE1497-Editar.jpg composition could be improved here too. The person in the background is distracting and doesn't add to the "story". You also have a couple of partial product labels which need to be edited out.
This series shows promise, and with closer attention to composition and focus, you could get some images accepted.
I'll stop there, I simply suppose that all your assets have exposure problems. In addition, I've seen noise, and probably IP related issues, as your ingredients and recipients are not neutral.
